Rexroth A2FM90 Hydraulic Main Pump Axial Piston Metering Motor
Product Description:
The Rexroth A2FM90 is primarily designed and sold as an axial piston fixed motor, though some suppliers market variants that can operate as a fixed displacement pump. It features a bent-axis design and is renowned for its high power density and efficiency in heavy-duty applications. A2FM90 as a Motor The most common configuration for the A2FM90 is as a fixed displacement motor in hydrostatic drive systems. Its primary function is to convert hydraulic fluid flow and pressure into rotational mechanical energy (torque and speed). Operation: The output speed is directly dependent on the flow rate from the supply pump and the motor's fixed displacement. The output torque is proportional to the pressure differential across the motor and its displacement. Key Motor Features: High Starting Efficiency: The design allows for excellent torque delivery even at low speeds. Robust Construction: Features one-piece pistons with piston rings for sealing and durability in demanding environments. Versatile Circuits: Suitable for use in both open and closed hydraulic circuits. A2FM90 as a Pump While less common than the variable displacement A10VSO series pumps, the A2FM90 unit can be configured as a fixed displacement pump to generate consistent flow in a system. Operation: When used as a pump, it converts mechanical power from an engine or motor into hydraulic energy (flow and pressure). Key Pump Features: Fixed Displacement: Provides a constant flow for a given input speed, unlike a variable displacement pump that can adjust flow on demand. High Pressure Capability: Capable of generating high pressure for demanding applications.
